THE EYE & THE BODY Ocular Manifestations of Systemic DiseasesDr.Turki AL-TurkiConsultant Ophthalmlogist
Flame shaped hemorrhages Cotton wool spots Hard exudates Flame shaped hemorrhages
Central retinal vein occlusion Grade IV Hypertensive Retinopathy Branch retinal vein occlusion • Second most common cause of vascular-related visual loss. • Risk factors • Hypertension • Coagulopathy • Vasculitis (Behcets,sarcoidosis,AIDS,SLE)
Cardiovascular diseases Diagnostic workup • BP measurement • Lipid profile • ECG • Echocardiography • Carotid Doppler Consider risk factors • Hypertension • Carotid artery diseases • Cardiac Arrhythmias • Coagulopathy Central retinal artery occlusion OCULAR EMERGENCY
Diabetes Mellitus • A cause of 4000 new case of blindness/year. • Risk factors • Family history • Duration of disease • Type of DM • Use of insulin • Poor metabolic control • Presence of Co-morbid conditions • Hypertension • Hyperlipidemia • Renal disease • Smoking • Alcohol consumption • Anemia • Obesity • Pregnancy
Mild non-prolifrative diabetic retinopathy Moderate non-prolifrative diabetic retinopathy Sever non-prolifrative diabetic retinopathy
Argon laser pan-retinal photocoagulation (PRP). • Focal laser treatment for macular edema. • Intravitreal injection of steroids • Intravitreal injections of anti-vascular endothelial growth factor (Anti-VEGF)
Diabetes Mellitus • Third (Oculomotor) cranial nerve palsy. MAKE SURE THAT THE PUPIL IS NORMALLY REACTING IN 3RD NERVE PALSY Complete 3rd nerve palsy
Thyroid eye disease Unilateral lid retraction Unilateral proptosis Bilateral lid retraction Bilateral proptosis In 50% of cases
Thyroid eye disease 1. Soft tissue involvement • Periorbital and lid swelling • Conjunctivalhyperemia • Chemosis • Superior limbic keratoconjunctivitis 2. Eyelid retraction 3. Proptosis 4. Optic neuropathy 5. Restrictive myopathy
Proptosis • Occurs in about 50% • not influenced by treatment of hyperthyroidism Axial and permanent in about 70% May be associated with choroidal folds Treatment options • Systemic steroids • Radiotherapy • Surgical decompression
Soft tissue involvement Periorbital and lid swelling Conjunctivalhyperaemia Superior limbic keratoconjunctivitis Chemosis
Optic neuropathy • Occurs in about 5% • Early defective colour vision • Usually normal disc appearance Caused by optic nerve compression at orbital apex by enlarged recti muscles Often occurs in absence of significant proptosis
Restrictive myopathy • Occurs in about 40% • Due to fibrotic contracture Elevation defect - most common Abduction defect - less common Depression defect -uncommon Adduction defect - rare
Inflammatory conditions (Sarcoidosis) • Idiopathic multisystem disorder • Characterised by non-caseatinggranuloma • More common in women 20-50 yrs • More common in blacks and Asians • Eyes – 30%
Inflammatory conditions (Sarcoidosis) • Anterior segment lesions (30%) • Conjunctivalgranuloma • Acute or chronic uveitis • Lacrimal gland involvement& dry eye • Posterior segment lesions (20%) • Patchy venous sheathing • Cellular infiltrate around vessels • Chorioretinalgranulonmas • Vasculitis • Neovascularisation • Infiltrate in vitreous (vitritis)
Sickle cell retinopathy Hyphema New vessel formation Sea fan neovascularization
Leukemia Sterile hypopyon White centered hemorrhage (Roth’s spot)
Metastasis Metastatic lung cancer Metastatic renal cell carcinoma Metastatic lymphoma
Neurofibromatosis type-1 (NF-1) Café-au-lait spots Most common phacomatosis Affects 1:4000 individuals Presents in childhood Appear during first year of life Increase in size and number throughout childhood
Eyelid neurofibromas in NF-1 Nodular Plexiform May cause mechanical ptosis May be associated with glaucoma
Intraocular lesions in NF-1 Lisch nodules Congenital ectropion uveae Very common - eventually present in 95% of cases Uncommon - may be associated with glaucoma Choroidal naevi Retinal astrocytomas Rare - identical to those seen in tuberous sclerosis Common - may be multifocal and bilateral
Very common - presenile cataract Ocular features of NF-2 Common - combined hamartomas of RPE and retina
Peripheral corneal involvement in Rheumatoid arthritis,Wegenergranulomatosis, polyarteritisnodosa Without inflammation With inflammation • Chronic and asymptomatic • Circumferential thinning with intact • epithelium (‘contact lens cornea’) • Acute and painful • Circumferential ulceration and • infiltration Treatment - systemic steroids and/or cytotoxic drugs
GIANT CELL ARTERITIS Systemic signs & symptoms • Headache • Scalp tenderness • Thickened temporal arteries • Jaw claudication • Acute visual loss • Weight loss, anorexia, fever, night sweats, malaise & depression Ocular Complications • Transient monocular visual loss (amaurosisfugax) • Visual loss due to • Central retinal artery occlusion (CRAO) or • Anterior ischaemic optic neuropathy (AION) • Visual field defects
Systemic infections • Tuberculosis • Syphilis • HIV • Toxoplasmosis • Brucellosis • Herpes zoster • Candida infection • Can affect any part of the eye • Lids optic nerve. • Can be limited to the eye only Difficult Dx • Requires systemic antimicrobial therapy PLUS Steroids • Can cause severe visual loss secondary to inflammation and infection.
